Capacitors at Tweeters

I’ve noticed that many Swiftlet farmers don’t know the purposes and usage of capacitor at the Tweeters. They just follow what others did “Monkeys see Monkeys do”. Even those who sell Tweeters with Capacitors know very little about the function and its effect, can’t blame them as most of them are not familiar in sound effect.

If you ask should you add capacitors in all the Tweeters in your Bh? My answer is YES, provided  you know how it works and what type of capacitors to be used. Adding capacitors on tweeters improves sound quality, extend the life of the Tweeters, etc by maintaining the flow of electric and sound wave. (Dielectric)

If you simply attached them on the tweeters just because you see many are doing it then my advice is NO .Without having the correct capacitors it would defeat the purposes, furthermore it would have adverse effect on the sound quality and tweeters.

There are many type of capacitors in the market and all of them have different usages, bear in mind not all are for sound purposes. The below would tell you what is sound & it measures.

To make the most of this article it would help if to give you a basic understanding of sound waves.

A vibrating speaker sends a wave of pressure fluctuations through the atmosphere. When the fluctuating waves reach your ears, they vibrate your eardrums backwards and forwards and your brains interpret this motion as sound. We hear different sounds from different speakers because of variations in sound wave 'frequency' - A higher sound wave frequency simply means that the air pressure is fluctuating faster.

We hear this as a higher pitch (or higher note). When there are fewer fluctuations over a given length of time the pitch is lower. These fluctuations are referred to as 'cycles' and measured as 'cycles per second' or Hertz.

Most speakers are only capable of working well over a certain part of the audible frequency which is 20hz to 20khz. Therefore selecting speakers within this range would give you added advantages. (Most swiftlet sounds are between these frequencies.)

Midrange speakers unsurprisingly produce a range of frequencies in the middle of the audible spectrum. It produces best quality of sounds between 100hz and 2khz.

Tweeters tend to be the smallest and lightest speakers and due to the limitations of their mass and size are totally incapable of producing sound frequencies much below 1khz.

I am not going to go into the technical aspect of it which would take pages to finish. (Dielectric loss and absorption, Electrolytic, Electrolytic resonance, etc.)

The common mistake made by most is without observing the polar of the capacitor. It is not advisable to attach the Non-bipolar capacitor to the tweeter +/- plates without observing its polarity it would defeat the purposes of the capacitor. Somehow I discovered many are doing it.

Capacitors have 2 legs the positive and negative. If you ask those who sell tweeters and most of them will tell you all are the same and it could be attached either ways positive & negative. This only applies to bipolar capacitors as both legs can be attached to either side of the tweeter +/- plates. (Non-bipolar capacitor you have to follow the polar +/-)

How do you know which legs of the capacitor is positive? Compare the 2 legs of the capacitor the one that is longer is positive.

For those capacitors that have the same length of legs the side on the capacitors which indicates its specification is the positive side.

Secondly make sure the capacitor value (uf) matches the crossover frequency.

Crossover frequency                        Capacitor Value (uf)

310                                                        134

402                                                        110

520                                                        80

(You will not always be able to get capacitors to these exact values, look for the nearest value. This is not rocket science and just by fitting a capacitor of approx the right value you will see an enormous difference)

So how to attach the capacitor to the tweeter? The negative leg of the capacitor attaches to the positive of the wire from the amplifier and the capacitor positive leg attached to the tweeter positive plate.

Why want to waste money buying additional capacitors to attached to tweeters if it doesn’t serve the purpose?

Good swiftlet farming all!

并不是什么硝酸鹽! 是生意

燕窝的價格激烈地下降自从最大的買家中國停止了購買和禁令了馬來西亞的EBN(可食燕窝)。 這影響了許多燕屋主和那些在這个行業直接或間接介入的人。




现在最大的挫折是就算乘搭飛機由人手提式也被禁止。 那就是说所有馬來西亞的EBNs完完全全被禁令。



把责任推到EBN里的硝酸鹽含量在是指定的原因，或許很多人被影響和瞭解硝酸鹽就是這个浩劫唯一的理由。



您是否知道我們邻国，就说说几个，印尼、越南、泰國等等都來這里購買我們的EBN (未加工的和已被處理的)和標記为他們各自國家的名字和出口到中國，不用任何制約。



原因是什麼...？



硝酸鹽是代罪羊...是的，您可以怪罪于它，因為它是任意由於所有的。 那些在这个貿易有連接的那些人就知道我的意思是什麼。 我們都知道，在这个圈子的那些VIPs也知道。 它是一個非常敏感的课题。 我也許会有麻煩。 那些在協會和部门的大人都知道它不止是硝酸鹽那么简单，因为所有的燕窝(被處理的和未被加工的)從所有亚太區國家所生產的EBN都含有硝酸鹽的。 您会很驚奇，因为一些燕窝里硝酸鹽的含量比馬來西亞EBN的甚而更高，但是他們仍然沒有被制約進口到中國。 (來源： 内部情报)



那么現在的原因是什麼… ？ 想想!



許多讀者有打电话给我並且想卖掉他們的燕窝因为很担心燕窝的價格会進一步的下降。 如果我是他們我會保留它，除非您是非常的需要金錢。 這是赚钱的时候。 这样的机会有多頻繁会到來？ ？ ？ ？。 在低价購買然后出售高价。這不就是像股市一样吗？



馬來西亞的EBN是以它的質量为名的，並且在亚太這個區域給我們的競爭者许多困难时期。 现在因为這个硝酸鹽問題我們的邻国從它得到非常多的益处。 现在許多人利用這個問題增加產業和把馬來西亞的EBN的名字推向更低来受益于它。 这永远是回到憎多粥少或者是粥多憎少的原理。 EBN的零售价在中國未见得走下坡...但是为什么馬來西亞的EBN和未加工的燕窝遭受到吹動...想一想吧!



明显地，它是介入了骯髒的企业戰術，政治，… 等等，就算燕屋农场也逃不过这个劫数。



不要擔心，任何一样东西下了一定会向上。 不是全世界的國家都有生產EBN只是極少的數量。

No It is Not Nitrate! It is Business

The prices of Nests have dropped drastically ever since China the biggest buyer had stopped to purchase and banned EBN (Edible Birds Nest) from Malaysia. This has affected many Swiftlet farmers and those who are involved in this industry whether directly or indirectly.

Now the biggest setback is that even hands carry by individual who travel by plane is prohibited. That means all Malaysian EBNs are totally banned.

Blamed on the Nitrate content in the EBN that was the reason given or many had being influenced to make understand that Nitrate was the sole reason behind all these havocs.

Did you know our neighboring countries to name few, , Indonesia, Vietnam, Thailand, etc are coming here to purchase our EBN (Raw & Processed) and labeled with the names of their respective countries and export to China without any restriction at all.

So what the catch ..?

Nitrate was the scapegoat..yes you could blame on it because it free for all. Those who had connection in this trade know what I mean. We know it so do all those circle of VIPs. It is a very sensitive issue. I might get in to trouble. The Big shots in the Association and the Ministry know it too it is beyond just Nitrate as all nests (processed & raw) from any country in this region that produce EBN contain Nitrate.  You would be surprised some of their Nests even have higher Nitrate content than the Malaysia EBN and yet they are no restriction to import to China.

(Source: Insider information)

So what the catch now…? Think!

Many Readers had called me and wanted to depose off their Nests fearing that the price would even drop further. If I were them I would keep it, unless you are desperately in need of money. This is the time to make money. How often does this type of opportunity comes????. Buy at low price sell at high price later..Isn’t this is like stock market?

Malaysian EBN is renowned for its quality and this gives our competitors in this region a hard time. Now with the Nitrate problem here our dearly neighboring countries had benefited so much from it. Now many had capitalized on this issue to push down this industry and the name of Malaysian EBN to benefit from it. It will always go back to more man less share and less man more share. The retail price of EBN in China has not gone down much..why Malaysia EBN & Raw nests here suffer the blow..think about it!

Obviously it’s involved dirty business tactics, politic,…etc which Swiftlet farming  couldn’t escape from it.

Don’t worry whatever goes down must come up. Not all countries in the world produce EBN  only a handful.

Good Swiftlet Farming All.

燕屋農場是關於您明白您自己的燕屋農場- 要聰明!

燕屋農場是涉及堅持不懈和忍耐。 它也是關於有能力辨認什麼對您的燕屋農場有益和堅持地继续使用顯示有好結果的任何產品或技術。

但是許多燕屋主卻沒有這麽做。 一旦一個有利的結果顯示了，他們就立刻停止持续他們以前所做的一切。 他們有平衡的傾向，我想知道他們是否為他們自己訂了一個極限或這是純淨的愚蠢。

我許多的讀者之前有打過電話問我關於這一點，這並不是新聞。 我不喜欢寫這一些，但是他們继续再次重複同一個錯誤。

Alor Setar的G先生今天早上打電話給我要求幫助。

G先生：      James你好吗? 我是A.Setar的G先生。

James：       很好，收到你的來電。 您好嗎？ 有一陣子未收到你的來電了。 您的燕屋農場做到什麽樣？

G先生：    最近不是那么好。 想請您幫忙…

James：    最近不是那么好？ .....您的意思是上次是好的，但是現在這不那麽好？

G先生：      是的，上次它有40個燕窩，但是到現在幾乎是一样沒有增加的。 為什麼James？我的燕屋農場是不是有某些事錯誤的？

James：       它真的是很奇怪的。 我记得您的燕屋農場一開始就有很好的成績。 您對您的燕屋農場做了什麼 ？ 据我所知您的燕屋農場到現在開始了大约有10個月的實踐了。

G先生：      是的，在連續的使用Love Potion以後，在最早的4個月它有了40個燕窩。 但是到現它沒有增加了。 為什麼James？

James：       它不可能的，…增加到40多個燕窩，但是到現在突然停滯，一定有某些事不對。 您是否有做裝修？ 您是不是聼了您的朋友或一些師傅做了某事或增加了某事在您的燕屋農場？ 您想要我幫助您，您必須说实话，否則我是无法幫到您的。 我不是開玩笑，如果您不矯正您燕屋農場的問題，再過幾年的時間您的燕屋農場也可能好像現在保持40多個燕窩。

G先生：      是的，James我是做了一些事在我的燕屋農場 ....... 在我的燕屋農場達到了40個燕窩之後，老實說我停止了使用Love Potion。 我聼我的朋友說我換了另外一個芳香。 從那之後它每個月只有增加1個燕窩。

James：       您不可以隨便使用從市場上的芳香。 現在是有許多品牌。 您自己可以看見它的不同。使用了Love Potion之後，從開始到4個月就可以有40多個燕窩。 您為什麼想要改用其他的芳香呢？ 如果您继续使用Love Potion，到現在它可能有100或更多的燕窩了。

G先生：      這是我第一個燕屋農場，我以爲全部的芳香都是相同的，而且我使用的那個是Love Potion一半的價格，並且我所有的朋友都強烈鼓勵我使用這個更加便宜的芳香。 他們說是很好的。

James：      是好嗎… ？ 那麽您朋友的燕屋農場有多少個燕窩呢….？

G先生：      哦 ..... 他們2個和我一样同一個時間開始的..10個月到現在有少過5個燕窩。 另外一個開始了3年的時間到現在有40個燕窩。 他們的燕屋農場從開始到現在都是使用那個便宜的芳香。

James：      G先生，您是非常聰明的......您正是一個天才。您或許將是一個非常成功的燕屋主，但是不是現在，是50年之後的燕屋農場。 您的燕屋農場開始的那么好就是用了Love Potion，但是您卻把它殺害了。

G先生：      50年之後？ 我不會在這裡。

James：      或許50年之後，燕屋農場不再是賺錢的。 那麽就沒有人做它，所有的燕子將去您的燕屋農場啦….哈. .哈。.哈。

G先生：      哎呀…我現在明白了…我為什麼沒有注意到呢。 現在我想起啦，自從我改用了那百多零吉的芳香之后，我燕屋農場的燕窩增量在每個月是一個，有時候還沒有呢。 我犯了一個大错误啦。 哎呀，都是我的朋友不好啦。一直叫我使用還說是最好的芳香，並且是很方便使用的。 我對燕屋農場不是很明白，他們這樣使用我就跟啦。 真是KNNB….@#%*%!。真得不能听他們說。

James：      不要責備他們G先生，也是您的錯誤。 您是不够細心。 一切都是在您的面前，但是您就是捉不到它的原理。 您已經看到了好的結果，在4個月就到達了40個燕窩…您為什麼要停止使用呢？那不是很愚蠢嗎？ 我還以為您是故意要停止的… 哈。.哈。您設了有限的配額… 哈。.哈。。可能您的朋友是非常純熟來如何防止燕窩增長。

G先生：      James不好那麽說啦 .....我現在已經知道。我現在應該做什麼…請幫我。

James：      收穫所有沒有燕子蛋和小燕子的燕窩。 立即停止使用那百多零吉的芳香。 噴洒雙重劑量的Love Potion來排斥早先芳香的氣味。 也噴洒在所有的牆壁和地板上。 您需要這樣做來排斥早先芳香的氣味。 您必須在在每2個星期噴洒，連續的噴2個月，這樣做您的燕窩將會增加。 现在您學會了，千萬不要隨便相信別人的教訓。

G先生： 他媽的我的朋友啦….KNNB#$@%& $#一直鼓勵我使用那個芳香(XXXX)。 請盡您所能，趕快把Love Potion寄來給我。

James： 很抱歉G先生，我只可以下星期才寄Love Potion給您，現在有的貨都是被人預定了。 有貨了我再通知您。 而且您已經浪費了6個月的時間，一個星期又是什麼呢？

G先生：      您就是喜歡取笑我啦，師傅 Sifu？

James：      如果我不是這樣做您又如何可以學會呢？

G先生：      哈. .哈。 您說得有道理。 非常感謝您。 當您有空來到A. Setar一定要告诉我，我請您吃一頓大餐….一切都抱在我身上。

James：   我會告诉您如果我是去那裡。 保重，不要隨便听其他人說。自己看見，要細心，要尖利….沒有人比您更加明白您的燕屋農場。

G先生：   是的。好的師傅…。好的，好的。.我現在已經知道了。

在外面還有許多好象他一樣的人，仍然在重複他們的同一個差錯… 我希望他們學得會。

要聰明! 您就不會出錯。
